You should be able to do this very easily yourself. Just put the engine at TDC for cylinder # 1 and remove the old distributor (keeping track of where the rotor pointed to the # 1 cylinder plug wire). Insert the 123 dizzy lining up the rotor so that it points in the general position of the old one, then connect the new electrical wires. With the ignition on, rotate the dizzy housing so the green LED inside the body of the dizzy just illuminates (keeping in mind the position of the # 1 cylinder). That should allow the engine to fire the first time.
My 123 is USB and not Bluetooth - but bet the way you upload the advance and vacuum curves is similar. You should start by searching for the Bosch dizzy curves here on the FAQ - believe they have been posted before - OR someone may have provided their 123 settings (degrees and RPM).
